Abstract
The utility model discloses an improved insulating pipe. The insulating pipe is provided with an inner pipe and an outer protecting layer, heat insulating material is filled between the inner pipe and the outer protecting layer, the outer protecting layer adopts a metal sleeve, and a retaining rib is formed on the surface. The retaining rib is helical. Because the outer protecting layer adopts the metal sleeve, the ageing resistance and the durability of the insulating pipe are greatly enhanced, the metal sleeve is matched with the heat insulating material, and the sealing property of the product can be ensured; the retaining rib formed on the surface ensures the outer protecting layer to achieve the enough intensity at thinner thickness, the anti-pressure ability and the tensile ability are strong, and the operation effect is good.
Description
Technical field:
The utility model relates to a kind of thermal insulation pipe that is used for delivering liquid and gaseous medium.
Background technique:
Thermal insulation pipe is extensive application in daily life, and city thermal pipeline, crude oil pipeline and central air-conditioner etc. all will be used thermal insulation pipe.The thermal insulation pipe kind of seeing in the market is more, wherein a kind of preferably thermal insulation pipe of effect is made of interior pipe and outer protective layer, be filled with hard polyurethane foam material (also claiming PU) between interior pipe and the outer protective layer, the outer protective layer of this thermal insulation pipe is metallic material or PE material, if it is too thin, the outer protective layer strength deficiency is out of shape because of pressurized easily; And blocked up, will increase substantially production cost of products again.In addition, outer protective layer adopts the PE material, also is easy to generate problem of aging, causes the thermal insulation pipe lost of life.
The model utility content:
The purpose of this utility model is the deficiency that exists at prior art and a kind of improved thermal insulation pipe is provided, the thinner thickness of its outer protective layer, but intensity is higher, is not easy to be out of shape because of pressurized.
For achieving the above object, thermal insulation pipe of the present utility model has pipe and outer protective layer in one, is filled with thermal insulating material between interior pipe and the outer protective layer, and described outer protective layer is a metal sleeve, and its surface forming has stiffening rib.
As improvement of the technical scheme, described stiffening rib is shape in the shape of a spiral.
As further improvement in the technical proposal, described stiffening rib and the moulding of outer protective layer integrated punching.
Described thermal insulating material is the hard polyurethane foam material.
Described thermal insulating material is hard polyurethane foam material and calcium silicate, wherein, pipe outer end in calcium silicate is coated on, the hard polyurethane foam material is then between calcium silicate and outer protective layer.
Described outer protective layer surface scribbles rust proof paint.
The beneficial effects of the utility model are: because outer protective layer adopts metal sleeve, make the ageing resistance of thermal insulation pipe and serviceability greatly improve, metal sleeve and thermal insulating material cooperate, and can guarantee the sealing of product again; And the stiffening rib of outer protective layer surface forming then makes outer protective layer to reach enough intensity with thin thickness, and the resistance to compression resistance to tension is strong, and using effect is good.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is a schematic appearance of the present utility model;
Accompanying drawing 2 is one of sectional structure chart of accompanying drawing 1;
Accompanying drawing 3 be accompanying drawing 1 sectional structure chart two.
The component symbol description:
Pipe in the 1-; The 2-outer protective layer; The 21-stiffening rib;
The 31-polyurethane foam material; The 32-calcium silicate
Embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Need to prove: thermal insulation pipe length of the present utility model can be decided as required, and accompanying drawing 1 is represented only for embodying the utility model structure one trifle thermal insulation pipe to the accompanying drawing 3.See that accompanying drawing 1 is to shown in the accompanying drawing 3: thermal insulation pipe of the present utility model has pipe 10 and outer protective layer 20 in one, and wherein, interior pipe 10 is a steel pipe, and outer protective layer 20 is sleeve shape, and is provided with one heart with interior pipe 10, and its material can adopt metallic material such as galvanized sheet and aluminium sheet as required.Be filled with thermal insulating material between interior pipe 10 and the outer protective layer 20, see shown in the accompanying drawing 2: thermal insulating material can adopt hard polyurethane foam material 31 merely; Shown in the accompanying drawing 3; It is calcium silicate 32 that thermal insulating material also can adopt internal layer, and skin is the pattern of hard polyurethane foam material 31, so that thermal insulation pipe can use under high-temperature condition.In addition, the surface forming of outer protective layer 20 has stiffening rib 21, and this stiffening rib 21 is shape in the shape of a spiral preferably, and the pressure that it can make outer protective layer 20 be subjected to evenly disperses, thereby makes outer protective layer 20 obtain best pressure-bearing tension effect.Stiffening rib 21 can be when impact briquetting outer protective layer 20, and is one-body molded with outer protective layer 20, promptly adopts suitable mold, makes outer protective layer 20 in the stamping forming while, and spiral stiffening rib 21 is outwards protruded on its surface.In addition, outer protective layer 20 surfaces also can be coated with one deck rust proof paint (color can be decided as required), so not only can strengthen the aesthetic property of thermal insulation pipe, and can prevent that corrosion phenomena from appearring in the surface of outer protective layer 20.
Thermal insulation pipe of the present utility model can be in bigger temperature range (50 ℃～140 ℃) use, heat insulation effect is good, aesthetic in appearance and be not easy distortion.
